Now that port status change notifications are interrupt-driven,
ehci-hcd needs to tell usbcore when a remote-wakeup resume operation
is finished -- we can no longer rely on the core to poll and find
out. This patch (as843) uses the root-hub status timer to force a
poll after the resume is complete.
The patch also changes the test for detecting when the TDRSMDN resume
period has expired. It's necessary to use time_after_eq() instead of
time_after(), since the polling is triggered precisely by a timer.
The same change is made for TDRSTR reset expiration, for consistency.

Switch ehci-hcd to use the new polling scheme, which reports root
hub status changes via the interrupt handler, in an asynchronous
fashion. Doing so disables polling for status changes (whose handler is
rh_timer_func).
Tested on a Geode GX machine, which is now capable of running at =~ 5
timer interrupts per second (in the -rt tree), resulting in significant

This patch (as710) adds a sysfs class-device attribute file named
"companion" for EHCI controllers. The file contains a list of port
numbers that are dedicated to the companion controller; by writing a
port number to the file the user can force a high-speed device
attached directly to the computer to run at full speed. (As far as I
know it is not possible to do this for a device attached to an
external hub.) A port is removed from the file by writing the
negative of its port number.
Several users have asked for this facility and it seems like a useful
thing to have. Every now and then one runs across a device which
behaves much better at full speed than at high speed.

ELAN's U132 is a USB to CardBus OHCI controller adapter,
designed specifically for CardBus 3G data cards to
function in machines without a CardBus slot.
The "ftdi-elan" module is a USB client driver, that detects
a supported CardBus OHCI controller plugged into the
U132 adapter and thereafter provides the conduit for
for access by the "u132-hcd" module.
The "u132-hcd" module is a (cut-down OHCI) host controller
that supports a single OHCI function of the CardBus
card inserted into the U132 adapter.
The problem with the initial implementation is that when
the CardBus card inserted into the U132 adapter has multiple
functions (and a CardBus card can support up to 4 functions),
it was the first function that was arbitrarily choosen.
The first batch of 3G cards tested, like the Merlin Qualcomm
V620, have two functions each supporting a seperate USB OHCI
host controller, of which it was that first function that is
wired up to the 3G modem.
Then along comes the Vodafone Mobile Connect 3G/GPRS data card,
aka "Option GT 3G Quad" as printed on it's rear or "Option N.V.
GlobeTrotter Fusion Quad Lite" as read with "lspci -v". And it
has the meaningful functionality in the second CardBus function.
That presents a problem because it was the "ftdi-elan" module
alone that knows how to communicate to the embedded CardBus slot
and the "u132-hcd" module alone that knows how to access the
pcmcia configuration and CardBus accessible memory space. And
of course, the information about attached (internally hardwired)
devices is contained within USB configuration embedded somewhere
within the CardBus card.
If only the "u132-hcd" module probe() interface could return a
result code that propagated back to the instigating function
platform_device_register() then the "ftdi-elan" module could
try an alternative CardBus function. However in spite of
the recent changes to the drivers/base/ routines that moved
device_attach() from bus_add_device() to bus_attach_device()
both of those routines lose the "failed to attach" 0 result
code and thus the calling routine, namely device_add() is
incapable of propaging the "failed to attach" condition back
to platform_device_add() and consequently back to the caller
of platform_device_register()
Experiments show that patching bus_attach_device() to return
ENODEV fails with the kernel locking up very early during
boot. But, however, if the patch is restricted to calls from
platform_device_add() then it does seem to work.
Unfortunately, until the kernel's drivers/base is properly
modified to propagate -ENODEV back to the caller of
platform_device_register(), it is necessary to "fix" the
"ftdi-elan" module by importing knowledge from the
"u132-hcd" module. This is the reason for the duplicated
functionality introduced in this patch.

I have found a problem where the root_port_reset() goes into an infinite
loop and stalls the kernel.
This happens when a hardware fault inside the machine occurs during a small
timing window. In case of USB device connection, if a USB device responds to
hcd_submit_urb(), and later the controller fails before root_port_reset(),
root_port_reset() will loop infinitely because ohci_readl() will always
return "-1". Such a failure can include ejecting a CardBus OHCI controller.
The probability of this problem is low, but it will increase if PnP type
usage is frequent. The attached patch can solve this problem and I believe
that it is better to fix this problem.

Certain boards seem to like to issue false overcurrent notifications,
for example on ports that don't have anything connected to them. This
looks like a hardware error, at the level of noise to those ports'
overcurrent input signals (or non-debounced VBUS comparators). This
surfaces to users as truly massive amounts of syslog spam from khubd
(which is appropriate for real hardware problems, except for the
volume from multiple ports).
Using this new "ignore_oc" flag helps such systems work more sanely,
by preventing such indications from getting to khubd (and spamming
syslog). The downside is of course that true overcurrent errors will
be masked; they'll appear as spontaneous disconnects, without the
diagnostics that will let users troubleshoot issues like
short-circuited cables. In addition, controllers with no devices
attached will be forced to poll for new devices rather than relying on
interrupts, since each overcurrent event would generate a new
interrupt.

When u132-hcd is built, it includes local header ohci.h, which appears
to have been intended only for use by ohci-hcd.
This throws warnings about functions which are defined and not used.
The warnings thrown are because three small functions are implemented in
the header, but not declared 'inline', a rather strange affair.
Since these functions are small, let's go ahead and define them as
'inline', just like the inline functions surrounding them. This makes
things more consistent, and kills the warnings.

This patch (as738b) fixes numerous problems in the controller/root-hub
suspend/resume/remote-wakeup support in ehci-hcd:
The bus_resume() routine should wake up only the ports that
were suspended by bus_suspend(). Ports that were already
suspended should remain that way.
The interrupt mask is used to detect loss of power in the
bus_resume() routine (if the mask is 0 then power was lost).
However bus_suspend() always sets the mask to 0. Instead the
mask should retain its normal value, with port-change-detect
interrupts disabled if remote wakeup is turned off.
The interrupt mask should be reset to its correct value at the
end of bus_resume() regardless of whether power was lost.
bus_resume() reinitializes the operational registers if power
was lost. However those registers are not in the aux power
well, hence they can lose their values whenever the controller
is put into D3. They should always be reinitialized.
When a port-change interrupt occurs and the root hub is
suspended, the interrupt handler should request a root-hub
resume instead of starting up the controller all by itself.
There's no need for the interrupt handler to request a
root-hub resume every time a suspended port sends a
remote-wakeup request.
The pci_resume() method doesn't need to check for connected
ports when deciding whether or not to reset the controller.
It can make that decision based on whether Vaux power was
maintained.
Even when the controller does not need to be reset,
pci_resume() must undo the effect of pci_suspend() by
re-enabling the interrupt mask.
If power was lost, pci_resume() must not call ehci_run().
At this point the root hub is still supposed to be suspended,
not running. It's enough to rewrite the command register and
set the configured_flag.
